Hi All !


I have a problem , I am trying for the Gateways & Gatekeepers exam.


My problem is that there are 2 different answers to my question in the Cisco Press Book.


It is about controlling the bandwidth needed for calls


say a call would need 64k (ignore headers and other stuff for now)


should I configure double the bandwidth for a session ?ie


bandwidth session zone localcall 128


or leave it at 64k


then there is the interzone.....


do I also need to double the bandwidth there too per allowed call ? ie


bandwidth interzone zone localcall 256


for 2 allowed calls ?

Hi,

up to my knowledge you always need to double the bandwidth when configuring GK.

let's say you have one call G711=80k

in the config:

bandwidth session zone localcall 160

or

bandwidth interzone zone localcall 160


Good luck with your exam
